Help!
Brenda's clock has suddenly decided to play silly b*ggers and go all dim. It's still working as you can (barely) see the digits in daylight but not at all when it's dark. Anyone got any ideas as to what the problem could be??
Cheers, Simon

Simon,
It maybe the LCD contacts from the printed circuit board- some just fail with time, but check the bulb first as David has indicated.
If the bulb is ok, remove the two recessed Phillips screws on the rear cover, lift off, feeding the bulb holder contacts through the casing.
The printed circuit board can then be lifted of the locating pegs.
Gently clean the upper and lower LCD strip contacts and refit, pressing the board fully home along these strips before reassembling.
You may like to carry out a mod on these clocks whilst dismantled to bypass the dim circuit, for improved daytime display brightness.
With the circuit board removed, spade electrical terminals facing towards you, and to the left. Bridge out the resistor on the upper left - adjacent to the black diode, with a piece of 15 amp fuse wire on the rear of the circuit board.
